SigNoz is an open-source observability platform unifying logs, traces, and metrics in a single application. It offers a cost-effective, self-hostable alternative to commercial APM tools like Datadog and New Relic, enabling users to monitor application performance, proactively identify issues, and rapidly troubleshoot downtime.

How It Works

Built natively on OpenTelemetry, SigNoz ensures vendor-neutral data collection. It integrates logs, distributed traces, and metrics, leveraging ClickHouse, a high-performance columnar OLAP database, for efficient storage and fast analytical queries. This architecture facilitates deep correlation between telemetry signals, providing richer context for debugging and performance analysis.

Quick Start & Requirements

SigNoz offers flexible deployment: a managed SigNoz Cloud service or self-hosted options via Docker or Kubernetes (Helm charts). It supports any language instrumented with OpenTelemetry. Comprehensive documentation is available at https://signoz.io/docs/.

Highlighted Details

• Unified Observability: Features include APM with out-of-the-box charts, Logs Management with powerful querying, Distributed Tracing visualized with Flamegraphs/Gantt Charts, customizable Metrics/Dashboards, and LLM Observability.
• Proactive Monitoring: Integrated alerting supports notifications on logs, metrics, and traces, including anomaly detection. Exception monitoring is automated for several languages.
• Performance: Benchmarks indicate lower resource usage than Elastic and superior high-cardinality data aggregation compared to Loki.
• OpenTelemetry Native: Minimizes vendor lock-in by building directly on the OpenTelemetry standard.

Maintenance & Community

An active Slack community supports users and contributors. Contribution guidelines are provided, and the project lists numerous maintainers across backend, frontend, and DevOps.

Licensing & Compatibility

The project's README does not explicitly state the software license. This omission requires further investigation for compatibility with commercial use or closed-source linking.

Limitations & Caveats

No specific limitations, alpha/beta features, or known bugs are detailed. The primary caveat for potential adopters is the absence of a clearly defined license, impacting deployment and usage decisions.
